摘要

公車捷運系統（Bus Rapid Transit，以下皆簡稱BRT）具有公車營運彈性與軌道捷運服務品質，其重要的特性之一即為專有路權。然而由於其公車的營運彈性，相配合車站及專用道基礎設施涉及配置擁有兩種可能方案：一是封閉式的設計，另一則是開放式的設計，封閉或開放式皆有其優缺點，因而在BRT發展規劃中，如何選擇決定開放或封閉系統，是一重要課題。
因此本研究將焦點放在BRT之封閉性與開放性策略分析上，藉由分析性數學方法（Analytic Mathematical Approach）進行BRT成本模式之建立，以最小系統總成本作為目標式，BRT之班距與站距為決策變數進行求解，藉由各式情境模擬與敏感度分析得知旅次需求、分布等環境因素對於封閉和開放式之BRT個別影響，並可代入該地區基本資料於本研究之模型求出開放與封閉式決策門檻圖，由已知之旅次起迄比例a、c與路廊長度L即可獲得BRT路線長度與較適宜封閉或開放營運計畫之相互關係，因此本研究所建構之模式可用以比較BRT封閉與開放式之相對效益，供決策較有優勢之類型。

Bus Rapid Transit, BRT, has either the flexible operation of bus and service quality of MRT. One of the characteristics is exclusive right way. There are two pattern of operation by the right acting in concert with infrastructures: closed form and open form. No matter which the pattern is there are some superiority and weakness. Therefore, how to make decision from closed or open form is a big issue.
The focal point is the strategy of open or closed form. The BRT modal was constructed by analytic mathematical approach, and has optimized headway and spacing by minimizing the total system cost. The relationship between the amount and distribution of demand and open-or-closed pattern can be clearly by baseline analysis and sensitivity analysis. Inputting the basic information in the modal can get the figure of open-or-closed threshold. By parameters of a and c which present the OD percentage, there are interrelation between BRT route length and operational design. Thus, this modal could compare the relatively revenue between open and closed BRT form, and guides the planner better one.
